Google announced it is opening up its Merchant Referral Program for Google Checkout. The new program was designed to encourage ecommerce providers to integrate Google Checkout into their shopping cart applications. Google is now opening up the incentive program to everyone who maintains a relationship with online merchants, including developers, web hosting providers and web designers.

Those eligible for the Merchant Referral Program will earn incentives for one year: 0.5% of all Google Checkout sales processed by the merchants they refer, and an additional $25 for each merchant that processes at least $500 in sales and 3 transactions with Checkout.
